Peaches of immortality

In Chinese mythology, Peaches of Immortality (Chinese: 仙桃; pinyin: xiāntáo; Cantonese Yale: sīn tòuh or Chinese: 蟠桃; pinyin: pántáo; Cantonese Yale: pùhn tòuh) are consumed by the immortals due to their mystic virtue of conferring longevity on all who eat them. Peaches symbolizing immortality (or the wish for a long and healthy life) are a common symbol in Chinese art, appearing in depictions or descriptions in a number of fables, paintings, and other forms of art, often in association with thematically similar iconography, such as certain deities or immortals or other symbols of longevity, such as deer or cranes.

The Jade Emperor and his wife Xi Wangmu (Queen Mother of the West) ensured the deities' everlasting existence by feasting them with the peaches of immortality. The immortals residing in the palace of Xi Wangmu were said to celebrate an extravagant banquet called the "Feast of Peaches" (Chinese: 蟠桃會; pinyin: Pántáo Huì; Cantonese Yale: pùhn tòuh wúih, or Chinese: 蟠桃勝會; pinyin: Pántáo Shènghuì; Cantonese Yale: pùhn tòuh sing wúih), celebrated on earth in honor (birthday) of Xi Wangmu on the 3rd day of the 3rd moon month. The immortals waited six thousand years before gathering for this magnificent feast; the peach tree put forth leaves once every thousand years and it required another three thousand years for the fruit to ripen. Statues depicting Xi Wangmu's attendants often held three peaches. And the Eight Immortals crossing the seas to attend the banquet is a popular subject in paintings.
